Calculating Area and Perimeter

Miss B explains how to calculate the area and perimeter of unusual shapes. She starts with a brief introduction and then dives into the concept of perimeter, emphasizing the importance of adding all side lengths. She provides examples and simplifies complex shapes into recognizable ones for easier area calculation. The video includes two examples, each demonstrating the process of calculating both perimeter and area. Miss B concludes by inviting viewers to ask questions.
